OBJECTIVE: To describe and validate a practical technique for sonographically
guided anterior cruciate ligament (ACL) injections.
DESIGN: Prospective,
cadaveric laboratory investigation. SETTING: Procedural skills laboratory in a
tertiary medical center. SUBJECTS: Ten unembalmed, cadaveric mid-thigh-knee-ankle
foot specimens (5 left knees and 5 right knees; 5 male and 5 female) from 10
donors aged 76 to 93 years (mean 85.6 years) with body mass indices of 17.6 to
42.2 kg/m(2) (mean 28.8 kg/m(2)). METHODS: A single, experienced operator used a
22-gauge, 63.5-mm stainless steel needle and a 12-3-MHz linear transducer to
inject 1.5 mL of diluted colored latex into the ACLs of 10 unembalmed cadaveric
specimens via an in-plane, caudad-to-cephalad approach, long axis to the ACL. At
a minimum of 24 hours postinjection, specimens were dissected, and the presence
and distribution of latex within the ACL assessed by a study co-investigator.
MAIN OUTCOME: Presence and distribution of latex within the ACL. RESULTS: All 10
injections accurately delivered latex into the proximal (femoral), midsubstance,
and distal (tibial) portions of the ACL. No specimens exhibited evidence of
needle injury or latex infiltration with respect to the menisci, hyaline
cartilage, or posterior cruciate ligament. CONCLUSIONS: Sonographically guided
intra-ligamentous ACL injections are technically feasible and can be performed
with a high degree of accuracy. Sonographically guided ACL injections could be
considered for research and clinical purposes to directly deliver injectable
agents into the healing ACL postinjury or postreconstruction.
